Mary - are you going to the Cancer Center? They seem to be so helpful on all areas. I have been there twice and they refused to give me more chemo in March even though my oncologist here in town almost insisted on it. As you said, it had to do with the quality of life.
I have tried Darvocet but got sick off of it. Am considering acupunture which they also do at the Cancer Center but it is so expensive here with no ins. help.
Each of us are different. My sister died 17 yrs. ago from breast cancer and she had a strong threshold of pain and would take little meds until the end. I am not like that and hope you don't feel weak because you are different from your mother.
God bless you in your decision.
